SNOW GUARD OR FENDER FOR ROOFS.

Specification of Letters Patent. Application filed December 6, 1907.

Patented April 14, 1908. Serial No. 405,320.

To all whom it may concern:

Be it known thatI, FRANcIs A. PETER, of N ewside, Washington township,in the county of Lehigh and State of Pennsylvania,

new and useful Improvements in Snow Guards or Fenders for Roofs; and Ihereby declare that the followclear, and exact description thereof,reference being had to the accompanying drawings, which form a part ofthis specification.

This invention is an improved snow-guard or holder especially adaptedfor use on tin roofs having standing seams, and its object is to providea guard which can be readily attached to such roofs without perforatingor puncturing the tin, or the seam.

The invention will be clearly understood from the following descriptionof'the guard illustrated in the accompanying drawings, in which a Figure1 is a top plan view of the guard. Fig. 2 is a side view thereof partlybroken. Fig. 3 is a front viewthereof. Fig. 4 is a vertical section online 44, Fig. 1. Fig. 5 is a horizontal section on line 5-5, Fig. 2; andFig. 6 is a section on line 66, Fig. 2.

The guard comprises a clamping-member adapted to be fastened to one ofthe seams, or flanges on theroof; and a holding-member removablyattached to the clamping-member.

The clamping-member is composed of similar but opposed plates 1, 1,which are preferably cast, provided with clamping ridges 1 on theirlower edges and opposed faces, between which edges the seam or flange Sof the roof-tin is embraced; and above the seam the plates areperforated as at l for the passage of a fastening bolt 2, provided witha nut 2 by which the plates are tightl clamped upon and to the seam orflange g by which the sheets of tin forming the roof are united in theusual manner. The bolt 2 it will be seen comes above the flange S sothat the latter is not injured by attaching the guard thereto.

The plates 1 may be longitudinally grooved as at 1 just above theclamping edges 1 as shown. They may also be provided with laterallyprojecting flanges 1 which will prevent the guard tilting or bending theseam S. The plates are also provided with tapered recesses 1 on theirouter faces, said recesses lying opposite and adjacent to each other,and forming a seat for the holding-member or snow arresting part 3 ofthe guard, which member is preferably of cast metal, and approximatelysemi-circular in contour, but can be made ornamental in form as shown,and is adapted to stand cross-wise of or straddle the holding member, asshown. The holding member 3 has a tapered recess or notch 3 adapted tofit upon the grooved portions 1 of the clampmg member, as shown in Figs.3, 5, 6, and when the holdingmember is in place the inclined sides 3 ofthe recess 3*, impinge against the oppositely inclined bottoms 1 of thegrooves 1 and thus the holding member tends to clamp the plates 1,together and u on the seam or ange S; while said holding-member is inturn upheld by the walls of the recesses 1 see Figs. 5 and 6. The partsof plates 1 through which bolt 2 passes are higher than the front partsof the plates, as shown at 1 so that the holding-member 3 is firmlybraced against the snow pressure by the parts 1 When the detainingmember is thus fitted to the clamping-member, it would secure the latterto the seam S, should bolt 2 work loose or be removed. I prefer howeverto use the bolt 2.

It will be seen that the holding-member extends on each side of theseam. In practice a row of such guards are attached to the seams acrossthe length or width of the roof, and will effectually in mass off theroof.

While especially designed for tin-roofs, the guards can be attached toother roofs having flanges or devices to which the plates 1 can beattached.

Having described my invention what I claim as new and desire to secureby Letters Patent is:

1. A detachable snow-guard for roofs comprising a clamping-member and aholdingmember, said clam rug-member being fastened to the roof an havingadjacent recesses in its opposite sides rovided with inclined bottoms,and a holding-member having a notch adapted to straddle the clamingmember and engage the recesses thereof, the inclined sides of thenotch engaging the inclined bottoms of the recesses in theclamping-member, substantially as described,

2. In a snow-guard, the combination of a clamping member composed of oposite plates adapted to engage opposite si es of a roof seam or flangeand clamp it, and formed with adjacent recesses in their outer faces;with a holding-member arranged transversely preferably of theclamping-member and having a notch in its lower edge adapted to engagethe reing-member and havmg a tapered notch encesses in theclamping-member, substanga ing the recesses m the plate, substantiallyas set forth. tia lly as described.

3. The herein described snow-guard for In testimony that Iclaim theforegoing as roofs having standing seams or flanges, and my own, I afliXmy signature in presence of the like, consistin of a two-piece clamingtwo Witnesses.
